SANITARY DIRT-GrUAIEtD FOR- HEATING-PIPES.

Patented Aug. 18, 1908.

To all whom it may concern:

Be it known that we, JAM S W. STOKER' and EDWIN S. JoNEs, citizens of theUnited States of America, and residents of the borough of Manhattan, city, county, and State of New York, and the city of Boston, county of Suffolk, and State of Massachusetts, respectively, have invented certain new and useful Improvements in Sanitary Dirt-Guards for Heating-Pipes, of which the following is a specification.

Our mvention relates to steam heating apparatus and comprises a guard or'covering for steam pipes such as are used in heating railroad cars and buildings, which permits the circulation of air, protects persons and.

objects from contact with the hot steam pi e and under ordinary conditions prevents the admission of dirt or water to the space in which thesteam pi es are inclosed.

In the case of rai way cars it is customary' to heat the same by lines of steam or'hot water pipes extending along the side of the car near the floor, below the seats. To prevent the passen ers from burning their shoes or clothing which might come in contact with these ipes it is necessary to cover the pipes. In or er that the air heated' by the pipes ma rise, and cooler air flow into contact wit the pipes for heating, it is necessary -that the covering or, guard, shall have openings through whichthe circulating air may.

ass. The diiiiculty heretofore has. been that these air openings also admitted dirt,

' the filth thus admitted to the mclosed space about the steam pipescould not be removed by the carcleaner, thus remaining'to breed.

.disease germs and unpleasant odors.

and water used in cleaning. the car, andthat We have invented a continuous sanitary dirt guard for such heating pipes which not only protects the passenger and admits of free GIIClllfitiOH of air, but also prevents the admission of dirt or water under all ordinary.

through the irt guard on line 22 of Fig. 1,

and Fig. 3 is a similar section of a modi tion.

Throughout the drawing similar reference figures indicate like arts.

1 represents the cor and 2 the side wall I curved upper portion 7, extending over the pipes to the wall 2 of the car. In the face of the shield are a series of horizontal slots, 8

and 9, the lower slot being marked 8. Inside of the shield are inwardly and upwardly inclined lips, 10, 10, connected to the vertical face of the shield at or near the lower edge of the slots 8 and 9, and extending to or about bn a level with the upper edge of said slots. The ends of these li s are connected at their ends to the shield by end ortions 11, 11, soldered to or cast, or 0t ierwise formed integral with the shield and lips 10, 10.

In the construction shown in Fig. 3, the end pieces are inclined to the shield instead of being at right angles to it. This permits the whole shield, lip and end pieces to be stamped out of a fiat sheet of metal.

In operation the parts being assembled as shown in Fig. 1, the shield protects the passenger from contact with the hot pipes The coldair passes in at. the lower slot 8 and the hot air out at the upper slot 9, but any falling dirt, splashing water or other foreign'matter thrown aboutthe car strikes the lips 10, 10,

etting behind the and is prevented from he shield may be shield or dirt guard.

madeiin sections and in case access to the pipes is desired any section may be removed y taking out the screws 6, 6. Of course other means of attachment for the shield may beused and the form of it varied so long as the horizontal slots and inner guard li s as described are retained to prevent the a mission of foreign matter. As shown, the dirt guard presents no sharp angles or recesses in which dirt may collect and from which it can be dislodged with difiiculty. Our dirt guard utilizes the sanitary curve at all points.

Having described our invention, what we claim is: l

1. The combination with the floor and the side wall of a car, and one or more lines of heating pipes running along said side Wall near the floor, of a covering for said pipes comprising a shield rovided 1n its vertlcal face with a horizonta slot approximately on a level with the lower portion of the pipe system and another slot above the level of the central ortion ofsaid system, sai shield provided with inwardly and upwardly in clined lips connected to the inner vertical face thereof near the lower edge of each slot and extending to about the level of the upperedge of each slot, and adapted to deliver an inwardly flowing current of air on said pipes. v

2 The combination with the floor and the side wall of a car, and one or more lines of heating pi es running along said side wall near the oor, of a covering for said pipes comprising a shield rovided in its vertlcal face with a horizonta slot approximately on a level with the lowerportion of the pipe system and another slot above the level of the central ortion of said system said shield provided with inwardly and upwardly inclined lips connected to the inner vertical face thereof near the lower edge of each slot I and extending to about the level of the upper edge of each slot, and adapted to deliver an inwardly, flowing current 0 air on said pipes,

said shield being also provided with end 1 pieces connecting the ends of said lips with the end edges of the slots. 3. The combination with the floor and the esaeao side Wall of a car, and one or more lines of heating pi es running along said side wall near the oor, of a covering forisaid pipes comprising a shield rovided in its vertlcal face with a horizonta slot approximately on a level with the lower portion of the pipe system and another slot above the levelof the central'portion of said system, said shield provider with inwardly and upwardlyinclinedlips connected to the inner vertical face thereof near the lower edge of each slot and extending to about the level of the upper edge of each slot, and adapted to deliver an inwardly flowing current of air on said pipes, said shield being curved outwardly at the bottom and adapted to tangential contact with the floor, and also curved inwardly at the top and adapted to connect with the wall above the pipes.
